I've been at grad school for 8 weeks now and hated almost every second of it. I feel stupid every seminar, class, homework. I'm not doing terribly gradeswise but I Know I contribute less than anyone else in my cohort in discussions. The rest of my cohort are 27+, I'm 22 having come straight from a three year degree. I'm in the social sciences and just feel I should quit, spend some time getting life experience and then potentially come back to it. I would hate to start hating my subject which I loved at undergrad but living on next to nothing for five years for this seems like a complete waste of time. I've moved from Europe to do this and would rather be making some money, living close to friends and family and not feel like an idiot every second of the day. However on the other hand a lot of people don't seem to enjoy grad school at first and get into it. I also don't want to disappoint my refereees who wrote strong letters of recommendation for me or the professors here who have been excellent. Any ideas
